Abstract:
This research explored the development of biodegradable mulch films utilizing
cellulose extracted from water hyacinth and chitosan derived from shrimp shells.
Traditional plastic mulch films, primarily made from polyethylene, pose a significant
environmental threat, contributing to soil pollution and microplastic accumulation,
while water hyacinth's rapid growth disrupts aquatic ecosystems. This study aimed to
address these issues by creating an eco-friendly alternative to conventional plastic
mulches, utilizing an abundant and problematic resource to mitigate plastic waste and
promote sustainable agricultural practices. The methodology involved extracting
cellulose and chitosan, preparing films, and outlining a plan for evaluating their
mechanical, physical, and biodegradation properties in future work.
The process included the extraction of cellulose from water hyacinth through bleaching
and alkali treatments, and chitosan from shrimp shells. Film preparation involved
incorporating varying chitosan ratios to analyze their effects on film properties. The
resulting films were produced, and a plan was established to subject them to
characteization, including assessments of their mechanical, physical, and
biodegradation properties, which will be carried out in future studies.
The intended findings of this research support the potential of these biodegradable
mulch films as a sustainable alternative for agricultural practices, offering a way to
reduce plastic pollution and utilize an abundant, underutilized resource. In conclusion,
this study contributes to the advancement of sustainable agriculture by providing a
biodegradable solution to mitigate plastic pollution and promote the utilization of
renewable resources, with the full evaluation of the films'properties to be completed in
future work.
